What kind of Mac do you have?

Virtual PC for the Mac has been pretty much discontinued, as you can now install Windows on all new Macs, either by dual booting with Boot Camp or virtually with numerous tools, including Paralels which is much cheaper tha Virtual PC was.

If you have an older PowerPC Mac then Virtual PC is the only realistic option I think. There are/were a few odd open source projects, but last I looked don't think they were really up to 'real world' use.
